UPDATE!!
Static Electricity now said to be cause of fire
Cell
Phone Blamed for NY Gas Station Fire
UPDATE:
New information gathered since the New Paltz refueling fire occurred
earlier this week, places the blame on static electricity as the cause
of the accident.
PEI (Petroleum
Equipment Institute) spoke with the New Paltz Fire Chief Patrick Koch
this week about the refueling fire and he made available two new pieces
of information about the fire that were discovered after an extensive
investigation of the scene and another interview with the victim,
Matthew Erhorn . First, although the motorist said that he chocked
the nozzle open with his gas cap (latch-open devices are not allowed
at the station in New Paltz), no gas cap was found at the scene. However,
a full Bic lighter was discovered two feet from where the car was
fueled. Furthermore, Erhorn later stated that he reentered his 1994
Isuzu Rodeo during the refueling process to look at his odometer and
then slid out of the vehicle to complete the dispensing process immediately
prior to answering his cell phone.
In view of this new information, New Paltz Fire Chief Koch issued
the following statement about the fire: "Upon further investigation
of the accident scene and another discussion with the victim of the
May 13 gasoline station fire in New Paltz, I have concluded the source
of ignition was from some source other than the cell phone the motorist
was carrying. Although we will probably
never know for sure, the source of ignition was most likely static
discharge from
the motorist himself to the nozzle dispensing the gasoline."
PEI has been studying the issue of refueling fires and static electrical
discharge at the gas pump since 2000 and has never received a confirmed
incident implicating a cell phone at a gasoline station anywhere in
the world. For more information please visit www.pei.org/static.

New Paltz, NY
— Matthew Erhorn, a student from SUNY, New Paltz is recovering from
burns after a fire at a gas station while he was refueling his Isuzu
SUV. Matt believes it was his cell phone that sparked the fire. If
true, this would be the first case where a cell phone actually ignited
a fire. Attempts to contact Mr. Erhorn were unsuccessful.
At
the ESD Journal, we believe there is a very remote change that a cell
phone could start a fire but it would not be from its own static charges
or its radio frequency signals. So many other things are much more
likely to have caused the fire. The cell phone's radio signals do
not have enough energy within them to start a fire. The cell phone
does not generate static charges while being used.
Fire
Chief Patrick Koch was quoted as saying that the problem was definitely
a cell phone that caused the explosion. A cell phone that was ringing,
and which Erhorn, 21, answered while he was pumping gas. At which
point, the area around the nozzle of the gas pump ignited.
Matt Erhorn was
pumping gas into his 1994 Isuzu at the Route 299 Courtesy Mobil station
at about 9:30 p.m. Thursday when he reached into his pocket and answered
his ringing cell phone. At which point, the area around the nozzle
of the gas pump ignited. The next thing he knew, there was a flash
of flame. He then threw the gas hose to the ground and began to run.
If it hadn't
been for some fast action on the part of the station attendant, the
explosion would have been a lot worse. The night attendant inside
the convenience shop, Mohamed Taiep, triggered the station's fire
suppressant system. In a second, the vehicle and everything else under
the station's canopy was covered with a white cloud of fire-snuffing
chemicals that made the station look like it had been hit by a snowstorm.
Chief Patrick
Koch, New Paltz Fire Dept said, "I'm positive today, that as
of last night, 9:30 last night, I'm positive that a cell phone can
ignite."
If true, The
New Paltz incident is the first recorded instance of a cell-phone
flare-up at a gas pump, according to Steve Fowler, a consultant in
the field of electrostatics.
Mr. Fowler stated
that the chance of the cell phone causing the fire is very remote.
It would have to have a battery problem causing overheating or rupture
of the battery which should have been noticed by the user. The sparks
which might come from a minor connection problem (especially during
the phone's ringing cycle) inside the phone would be highly unlikely
to have enough energy or distance to cause ignition. The vapors would
have to be in the right place with the right spark to have an ignition
of the vapors. Mr. Fowler went on the say that the most like causes
of such a fire is static or smoking. If smoking could be ruled out,
then static is by far the most common cause of such an accident. When
gasoline is pumped through the nozzle, static electricity is created.
This static is typically conducted harmlessly to ground by the connection
of the hose to the car. If this connection is broken, there can be
a static buildup, discharge and ignition right in the vapor rich space
around the fuel port area of the car. For more information on this
and other issues concerning refueling fires, Mr. Fowler may be contacted
at 864-574-6415, email: sfowler@sfowler.com.
By
assuming a cell phone caused the fire, the real cause may be overlooked
and be waiting for the next time to ignite.
1. The hose at
the gas station could have a broken connection to ground at any of
the many connectors in the system.
2. The Isuzu
may have a broken connection between the fuel port of the car and
the car body.
3. When Mr. Erhorn
when reached for the cell phone which was ringing, he may have broken
the connection of the nozzle and the car, or his hand and the nozzle
allowing a static discharge in the vapor rich areas.
Since Mr. Erhorn
could not be reached, we may never know for sure.
Many stories
of cell phones igniting fumes at gas stations began circulating in
the media and on the Internet since 1999. Those stories apparently
came from Asia, though investigators have not been able to backtrack
the anecdotes to the specific individuals or events.
Since then, a
good number of articles have been written that speculated on the subject,
though no definite cases have been uncovered. And some have done experiments
trying to create the proper conditions to ignite gas fumes with a
cell phone -- none of which appear to have been successful.
Signs warning
consumers to turn their cell phone off while pumping were posted only
inches away from where Erhron was actually pumping the gas. These
warnings are due to a code which states that any electronic device
used in an explosive or ignitable area must be explosion proof or
intrinsically safe. Since cell phones are not designed this way, the
manufacturers must state to not use them in explosive situations such
as gas stations.
Mr. Erhorn's
injuries were reported as minor burns or singing to one arm.
